Recieved my SR black fuses today for my amp, DAC and transport. Even after just a couple of hours they sound better than the stock fuses. I haven't played with direction yet, figured I'd let them burn in first. I thought my system was quite transparent before.....its even more so now. I don't have a mega buck system but it's sounding quite good and I'm pleasantly surprised that the fuses made an improvement right out of the box, and hopefully will get even better in time. My Decware Torii mkIV and PS Audio Perfectwave PMT and PWD got the new fuses and they feed my Tekton Double Impacts. So I've switched sides from fuse cynic to advocate. I realize this might cause sleepless nights for those that are so concerned over the use of audiophile fuses by others, but I couldn't help myself!
